Where the hell is Yin Xin?

As we know, the center of the earth is the intersection of the earth's rotation axis and the equatorial plane. So in the same way, the so-called galactic center refers to the intersection of the axis of rotation of the Milky Way and the galactic plane.

After the position of the sun in the Milky Way is determined, it is easy to determine the direction of the center of the Milky Way, that is, the direction of Sagittarius. As far as right ascension and declination are concerned, the year 2000 is right ascension17 45.6' and declination-29 00'. This "point" is not far from the northwest of Sagittarius "Gamma" star, close to the dividing line between Ophiuchus and Scorpio.

Because there are a lot of dust and opaque substances scattered between the position of the sun and the center of the Milky Way, it is difficult to see the silver heart with an optical telescope, let alone see it clearly. This requires the development of science and technology to make better telescopes to achieve this goal.
